Specification of Letters Patent.

Application filed August 31, 1910. Serial No. 579,998.

1 '0 all whom it may concern:

Be it known that We, CHARLES L. VANonnvonr, Orro J. PITT, and CHARLES. i VANDER- vonr, citizens of the United States, residing at Enderlin, in the county of Ransom and State of North Dakota, have invented certain new and useful Improvements in Automobile-Tires,'of which the following is a specification.

This invention comprehends certain new and useful improvements in resilient Wheels, and tires for automobiles, motor trucks and other vehicles and the invention has for its primiiry object a simple, durable and eiiitire which Will embody to a marked degree the requisite characteristics of resiliency Without being open. to the manifest objections incidental to the use of tires of the pneumatic. type.

With these and other objects in view as will more fully appear as the description proceeds the invention consists in certain constructions, arrangements and combinations of the ports thatwe shsli hereinafter fully describe and claim.

For a foil understanding of the invention, reference to be had to the foilowing description zind zicoonl anying drawings in which:

Figure 1 is at side elevation of zr'tirc const ucted in nccordznnxe with our invention port of one of the retoinin rings bein broken away; Fig: 9. is on edge View of tireportiy in section; Fig. 3 is a frogmen tot-y View of the periphery of the inner rim; and, Fig. 4 is e (ctoii perspective view one of the springs employed.

Correspomling and parts referred to in the following description and indicated in oil the views of the accompanying drowings by the some reference char-actors.

Our improved tire comprises an inner rim 1. and an outer rim 2- of mctai or any other desired substenceor materiel, said rims being concentric one to the other, in spaced relation to each other, and the inner rim being designed for attachmentto the teliy of a Wheel in desired way. The inner rim 1 is formed with outstanding and redialiy projecting circumferentiai side flanges 3 and with an intermediate circumferential by any desired mnnber of transversely extending ribs 5 whereby the peripheryof the inner riris divided into tWo sets of circnmferentially extendingsegmental slots 6. L

The outer rim 2 is formed with an inter mediate circumterentially extending rib 4" arranged in axial coincidence Wlth'tht: rib d and with a plurality of sockets 7 each one of which is set preferably midway the two adjacent transverse ribs will thus be understood that the sockets T are arranged in two series in theinner face of the rim 2 and on opposite sides of the inwardly projecting circumferential flange o1 said rim.

Bowed springs 8 are interposed between the inner and outer rims 1 and 2, said springs being of any desired number, according to the number of segmental slots 6 and corresponding sockets 7, the said springs being formed of any desired metal and be ing arranged so that their ends will project inwardly and ride in the slots 6 and ubiit 5 of the rim 1. It

under ficxion against the transverse ribs Thescsprings are respectively formed with nibs or iug's 9 intermediate of their ends. the said lugs being received in therespective Sockets 7 of the outer rim 2. Monitestly there. are two sets of those springs 8 one set on each side of the ribs 4,

To retain the ports togelher againstsidewise strain and disploceinent We have provided side retaining rings L0 which are secured against the opposite sides the iii-- ner and outer rims 1i. and in any desired Way as by screws 11 or similar fastening devices Working in bosses Formed in the outer rim 2, the inner edgcs oi' the rings overlapping the side edges ot th inner rim). if desired the outer rim 2 n be chnnneied as shown so as to necei :1. metal, wooden, robber trend element 12, although is to be understood thn't our invention is not limited to this construction and errongeme of pertsyor to the use of rubber at at is we do notdepend upon rubber to secure the sired resiiiency. Preferably the slio rings 10 are formed with inwordi nnlzir flanges i0 tit-ting w in the outer rim 2 and preferably of a width substantially equal to the Width of the opposing flanges of the inner rim 1. j

FZGHI the foregoing description in tion with the accompanying dram operation of our improved resilient til be apparent. in the practical use. 0"

extending 2H1- 'in the sockets 7 device, it is obvious that the outer rim QWlll be permitted to yield to secure the desired resiliency, as it is supported in spaced relation from the inner rim 1 by arched or bowed springs 8. It is evident that the parts may be easily made, and may be readily assembled, it being possible to easily slip the springs 8 into place with their lugs 9 seated and their ends bearing against the bottom walls of the segmental slots or channels (3. Then after the side rings are secured in place, the rim is complete and ready for attachment to the felly of a vehicle wheel.

Preferably, as clearly illustrated in the drawings, the springs of one set break joint with the springs of the other set, the transverse ribs being therefore duplicated for this purpose.

Having thus described the invention,what is claimed as new is:

1. A the of the character described, comprising inner and outer concentric rims arranged in spaced relation to each other, the inner rim being formed with circumferential side flanges and a circumferential intermediate rib spaced from said flanges and with a plurality of transverselyextending ribs intersecting the circumferential rib and dividing the periphery of said rim into two sets of circumferentially extending slots, the outer rim being formed on its inner face with a circumferential rib set opposite the intermediate rib of theinner rim, and bowed springs interposed between said rims on opposite sides of the intermediate ribs thereof and bearing against said rims, the .ends of the springs working in the slots of the inner rim and adapted to abut against the transverse ribs thereof.

2. A tire of the character described, comprising inner apd outer concentric rims, arranged in spaced relation to each other, the inner rim being formed with circumferential side flanges and'a circumferential intermediate rib spaced from said flanges and with a plurality of transversely extending ribs intersecting the circumferential rib and dividing the periphery of said rim into two sets of circumferentially extending slots, the

outer rim being formed on its inner face with a circmnferential rib set opposite the intermediate rib of the inner rim, bowed springs interposed between said rims on opposite sides of the intermediate ribs thereof and bearing against said rims, the ends of the springs working in the slots of the inner rim and adapted to abut against the transverse ribs thereof, and retaining rings secured to the opposite sides of said rims, the rings being formed with inwardly extending annular flanges fitting within the outer rim.

In testimony whereof, we a'lliX our signatures in presence of two witnesses.
